Logo of Adopter - the marketing agency for deep tech and climate adaptation.

Episode summary

Tim Rault-Smith, startup advisor and board member at SALINE Ventures, discusses startup scaling, product-market fit, and the realities of early-stage company building on Episode 10 of Scaling Green Tech, a podcast by Adopter.Rault-Smith draws on his experience as one of ForgeRock's earliest employees - a digital identity and access management company that grew from a distributed team of around 12 people to an IPO on the New York Stock Exchange in 2021, before being acquired by Ping Identity in 2023. He traces how ForgeRock started with no products of its own, relying on services revenue and early equity grants to hold the team together. He connects those lessons to his current work advising EV and clean energy companies, using 3ti and nodum as live case studies in how founders can test demand and sequence their route to product.This episode is relevant for deep tech and EV founders at early and growth stages, startup advisors, angel and venture investors, and operators in EV charging infrastructure who are navigating product-market fit, capital raising, and the transition from services to product business models.

Key takeaways

  • Founders routinely mistake interest for sales. A potential customer saying "that's interesting" is not validation. The right signal is a customer who can articulate how the product affects their bottom line and is willing to commit money to it.
  • Selling before you build is a legitimate strategy, not a shortcut. If you can demonstrate enough of a solution to get a pre-sale or early commitment, you have validated demand without the risk of building something nobody wants.
  • Every company is defined by where its revenue comes from, not what it calls itself. A company with a great product but service-dominated revenue is a services company. Founders should be honest about this distinction early, because it shapes hiring, investment strategy, and growth ceiling.
  • Starting as a services company is not a failure mode. It can generate early revenue, reduce capital dependency, and force commercial discipline - all of which make the eventual transition to product more sustainable.
  • Taking on too much capital before achieving product-market fit is one of the most common ways startups fail. Once the money is spent and the cap table is loaded, a pivot becomes structurally very difficult to fund.
  • Founders should do due diligence on their investors with the same rigour investors apply to them. Knowing where the money is coming from, whether it is actually available, and what strings are attached is not optional - it is a survival question.
  • Commitment in a startup is not just about hours. It is about understanding that the boundaries between work and personal life will be harder to maintain than in a corporate role, and being genuinely prepared for that before you start.
